At the Solid Rock Shop, Tony paid $19 for 3 pounds of the same type of stone. What did each person pay per pound and who made the btter buy?

Tiffany purchase the better buy.

Step-by-step explanation:

given data

Tiffany paid  = $38

snowflake obsidian = 9 pounds

Tony paid = $19

same type of stone = 3 pounds

solution

Tiffany shopped well in this scenario. Mainly because Tiffany paid less per pound than Tony. This can be calculated by dividing the total amount paid by the amount received by each

so for Tiffany

= $38 ÷ 9

= $4.22 per pound

and for Tony  

=$19 ÷ 3

= $6.33 per pound

so that here Tiffany paid $4.22 per pound and Tony paid $6.33 per pound

so here whole $2.11 more than Tiffany

so that with this Tiffany purchase the better buy.
